Way better than expected!
Got this thing because of the video. Was a bit skeptical. Just wasn't convinced this thing was going to work. So, imagine my surprise when it not only worked, but was wayyyyy more controllable than other ink spattering devices. When you use the ink sprays, control is an issue. It doesn't always go where you want it to go. With this device, you have much better control over where you are spraying, and the depth of color. If you focus the point close to the paper, the darker the ink. The further away from the paper, the lighter the ink. It was really nice to use a device that had better direction as to where the ink was going. No doubt, you have to play around with the pens a bit, but if you use the brush end of the markers, it really does a nice job of spreading the ink where you want it. With other techniques, it doesn't always go where you direct it.
